So how do you do cold wallets, exactly?

Buy a brand-new computer and never connect it to the internet?
Then write down the private key on a piece of paper?
And generate transactions offline and then use the generated QR link on an online computer?

And how do you do this for Ethereum tokens?

Trezor or ledger nano.
Or just a write the private key on a piece of paper

But how do you input that private key without it ever running the risk of getting on the internet?
A deconnected computer?

With a trezor, and I suppose the same is tru for the nano, the private key is generated on the device itself and is never revealed to the computer. When you send bitcoin, the trezor signs the transaction without revealing the private key

Thanks.
Still not sure though. Technically the private keys are on the trezor as well it seems.
